A cold, old dying star has been detected by a citizen scientist of NASA, which might deliver a window into the fortune of our soar system billions of ages from now. An anomaly was detected by a citizen scientist from Germany, Melina Thevenot, while searching through data collected by Gaia spacecraft of the European Space Agency. Initially, she thought it was not a useful data, but when the source in the images was looked by her from mission of Wide-field Infrared Survey Explorer of NASA, she thought the data may be valuable, and it was handed over to the crew working on Planet 9 citizen scientist mission.
To follow up the finding was decided by the leads of that project, to take a deeper look by relocating the Keck II telescope in Hawaii. The blip was not bad data, was confirmed by the by Keck II as all eyes were engrossed on the tiny spot in the sky. It was coldest and the oldest white dwarf ever spotted by us said the team, and a peculiar set of dusty rings is orbited to it. The discovery was published in the Astrophysical Journal Letters recently.
John Debes, the lead author of the study said that, our assumptions of how planetary systems evolve are actually challenged by this star. He also added that, this white dwarf is so ancient that whatsoevermethod is feeding material into rings must work on timescales of billion-years. As this white dwarf is much older as compare to the typical dusty white dwarf, which makes it so interesting. Debes said, with our present models it is really hard to explain of how exactly inner white dwarf system gets asteroids, but how to make that happen is well known by our Nature. Planet 9 of Backyard Worlds was launched in Feb. 2017 by educational institutions along with collaborating science and NASA.
